Industrial U2 1000W server supply

The Athena Power AP-2UMK10P868 is a single 1000W ATX 3.1 power supply built for workstations, edge servers and GPU-intensive platforms. It delivers continuous output with a 12V-2x6 connector for modern graphics cards and includes dual EPS 8-pin plus 8(4+4)-pin CPU connectors for dual-processor boards. The unit carries 80 PLUS Platinum certification and active PFC across a universal 100-240V input range.

Dual 60mm thermal-controlled cooling

Two ball-bearing fans adjust speed based on internal temperature, keeping the supply within its 0 to 50°C operating window while MTBF is rated at 100,000 hours at 25°C and full load. Efficiency exceeds 92 percent at typical loads, reducing waste heat and acoustic output compared to lower-rated units. Protections include OVP and OCP, and hold-up time is 17 ms at nominal input.

Replaces older ATX 3.0 or 2.x units lacking 12V-2x6

The jump is worthwhile when a build needs the PCIe 5.0 GPU connector, dual CPU power for server boards, or Platinum-grade efficiency for 24/7 operation. Builds staying on a single mid-range GPU with standard 8-pin power and no redundant supply requirement will not use the extra connectors or efficiency headroom.

Questions about this item

How do I install the 24-pin ATX and 12V-2x6 connectors without bending pins?

Align the 24-pin ATX (20+4) and 12V-2x6 GPU connectors squarely before pressing; the keyed shapes prevent reverse insertion. Route cables behind the motherboard tray first, then seat each connector firmly until the latch clicks. Do not force angled insertion — bent pins on the 12V-2x6 can cause 12V rail instability.

Which components need replacement first during long-term 24/7 operation?

The dual 60mm ball-bearing fans are the primary wear items; MTBF is rated 100,000 hours at 25 °C full load. Dust buildup reduces airflow, so clean fan blades and heatsink fins every 6-12 months. Electrolytic capacitors on the secondary side may drift after 5-7 years of continuous 1000W operation.

What thermal limit appears first when the unit runs at 1000W continuously?

At sustained 1000W the +12V rail delivers 82A and internal temperatures rise until the smart thermal control ramps both fans to maximum. The 50 °C operating-temperature ceiling is reached before any protection triggers; hold-up time remains 17 ms. Ensure chassis airflow keeps intake air below 40 °C to avoid throttling.
